Electron-Photon interaction associated Uncertaity Relation based Tunneling in a Parallel Double Quantum Dot System

A new mechanism of electron-photon interaction in a parallel double quantum dot (DQD) system is studied. The electron is allowed to transit between dots due to the electron-photon interaction. When the electron in quantum dot m (QDm) transits to the adjoining QDm(m,m1,2 and mm), it is allowed to tunnel into leadm , which is connected to QDm , via energy-time uncertainty relation in a very short time interval. Like the Kondo resonant peak in Anderson model, the new mechanism of the electron-photon interaction exhibits peaks which depends logarithmically on temperature. The character temperature obtained is found to be higher than the Kondo temperature in some situations. Unlike the Kondo effect, the quantum mechanical tunneling associated the electron-photon interaction is not always on resonance.
